Patent DE-19721992-A1 (DE)
Title: Liquid and gas flowmeter
Inventor: HOFFER OTTO DIPL ING
IPC: G01F1/698
Filed: 1997-05-26
Abstract: The flowmeter comprises a sensor (G) and one or more comparator resistances (P,R3) connected to two further fixed resistances (R1,R2) forming a Wheatstone bridge. A control circuit controls the bridge current by continuous bridge equalisation. A linearisation network, e.g. consisting of analogue multipliers or a microprocessor, is used to obtain a voltage value, which corresponds to the product of sensor current and sensor voltage. This value is squared to obtain a voltage value linearly proportional to the flow rate. A temperature dependent resistor is used to detect the temperature of the flow medium.

Patent DE-19842564-A1 (DE)
Title: Centrifugal sieve for the dewatering of fibrous mass
IPC: B01D33/15
Filed: 1998-09-17
Abstract: The centrifugal sieve has a facility for the subsequent washing of the retentate as a continuous operation. An upwardly convex sieve (8) is mounted on a conical rotor body (3) whose cone angle is 110-170 deg . The raw mixture is fed to the underside of the sieve through a line (10) onto a table (11) from where it is distributed over the sieve by rotating paddles (9).  The filtrate passes into a chamber (12) and is expelled through circumferential holes (13) into a chamber (14) from where it can drain. The retentate is removed from the sieve by a fixed scraper (16) which drops it onto a sloping plate at the base of the vessel. Where washing is required a wash water line of relatively small diameter passes concentrically through the hollow rotor shaft.  The raw mixture is fed from above around this pipe onto a distribution table. The wash water pipe, which is fixed to the rotor shaft and hence rotates with it, passes through this table and discharges the water onto another table and paddles. The principal filtrate and wash water filtrate are collected in separate chambers and discharged separately.
